It looks a bit small to me; there is no mention of the dimensions on the page. The website says it maintains 300c (570F). This is just a few degrees warmer than most home ovens get. And at $446 USD, it's pricey for what it does.

I'm amazed at some of the pizza other members here have cooked in their home ovens. Honestly, I think you can do better with your kitchen oven and a stone (for $50 USD or less); and you can probably find a stone locally.
